Could someone guide me on writing a smart contract? I think what I am looking for isnt so hard, willing to pay if necesary, sorry if this post isn´t allowed here. I read the FAQ And couldn´t find anything that said this isn´t allowed.

Hello! I tried to upload ETH via bitcoin in Ethereum Wallet, send it to adress that was shown, but closed the window with adress before I recieved ETH, so it was about 8 hours ago, and I still haven`t recieved it. Maybe someone had the same problem? Thank you
